A　new　organic-inorganic　hybrid　coordinated　polymer　[Zn(C8H23N5)](2)(Pb3I10)　(C8H23N5　=　tetraethylene　pentamine)　was　synthesized　by　hydrothermal　reaction.　it　crystallizes　in　triclinic,　space　group　P1　with　a　=　9.781(2),　b　=　11.442(3),　C　=　11.565(3)　angstrom,　alpha　=　99.075(8),　90.540(9),　gamma　=　109.967(5)degrees,　Zn2C16H46N10Pb3I10,　M-r　=　2399.94,　V　=　1198.4(5)　angstrom(3),　Z　=　1,　D-c　=　3.325　g/cm(3),　F(000)　=　1048.0,　mu(MoK　alpha)　=　17.951　mm(-1),　the　final　R　=　0.0412　and　wR　=　0.0993　for　3375　observed　reflections　with　I　＞　2　sigma(I).　The　title　compound　consists　of　[Zn(C8H23N5)](2+)　cations　and　anionic　chains　[Pb3I10](n)(4n-),　which　are　combined　with　each　other　via　electrostatic　attractive　forces　and　N-(HI)-I-...　hydrogen　bonds.
